LOADING AND UNLOADING APPARATUS.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed January 28, 1908. Serial No. 413,073.

To all whom it may concern:

Be it known that I, hLIIGHAEL G. Duonow, a citizen of the United Statesof America, re-

siding at Natchez, in the county of Adams 1 and State of Mississippi,have invented new and useful Improvements in Loading and UnloadinApparatus, of which the following is a spec' 'cation.

This invention relates to loading and unloadin -apparatus designedparticularly for use in oading and unloading boats in places where theWater is shallow, like some parts of the Mississippi river, and one ofthe principal objects of the invention is to provide a simple form ofaerial railway which can be quickly set up and taken down and which isquick and eflicient in operation.

Another object is to provide a device of the character referred to whichwill handle general freight quickly and convey it from the boat to theshore and from the shore to the boat.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawings, in which,-

Figure 1 is a plan view of loading and unloading apparatus made inaccordance with my invention. Fig. 2 is a side elevation of the same.Fig. 3 is an enlarged sectional view of the winding mechanism andshowing a modified form of carriage. Fig. 4 is a side elevation of thegeneral merchandise carrier. Fig. 5 is an end view of the same. Fig. 6is a side elevation of the traveling carriage. Fig.

7 is a plan view of the carriage. Fig. 8 is a side elevation of a cottoncarrier.

Referring to the drawings for a more specific description of myinvention, the numeral 1, Figs. 1 and 2, designates an anchor postdriven into the ground, and connected to this post is a rope or cable 2,said rope or cable passing up over a buck support 3. The cable 2 isconnected to a ring 4, and the main or trolley wire 5 is connected atone end to said ring and extends thence over a pulley 6 on a standard 7secured to the deck of a boat 8, and from thence the trolley wireextends to a Windlass or winding drum which will be hereinafterdescribed. A pulley block 9 is connected to the ring 4, and passingthrough said pulley is an outboard cable 16, said cable extending over agrooved roller 11 on the standard 7 and from thence extends to theWinding mechanism referred to. A carriage l l l 12 comprising spacedplates 13 between which grooved pulleys 14 are connected to the inboardcable 15 at one end and to the outboard cable 16 at the opposite end,the cable 15 extending over a pulley 17 on the standard 7 and extendingthence to the winding drum. The carriage 12 is provided with spaceddepending bars 12 in which are formed key-hole passages 12 for a purposeto be hereinafter set forth.

The winding mechanism comprises a frame in which three separate drumsare journaled, the drum 18 being utilized as the trolley cable drum,said drum being provided with a suitable brake lever 19, the drum 20being utilized for the outboard cable 16, While the drum 21 is used forthe inboard cable 15, said drums being also provided with a brake lever22. The drums of this winding mechanism may be connected by chains 23 toa suitable engine or motor under the deck of the boat.

Suspended from the carriage 12 is a general merchandise carrier 24comprising curved bars 25 and cross bars 26. A pivoted section 27 alsoprovided with cross bars 28 is hinged at 29 to the main section of thecarrier, and a suspending hook 30 is connected to the carrier at itsupper end and a latch 31 pivoted upon the pin 32 is adapted to engage across bar 33 on the section 27. There may be two of the latches 31, asshown in Fig. 5.

In the lower end of the carriage 12 a removable key 34 extendstransversely of the carriage, and suspended from the body of this key isthe hook 30 of the carrier, and this key is provided with a stud 34which may be passed through the keyhole passages.

As thus far described the operation of my invention may be brieflydescribed as follows: After the apparatus has been set up, as shown inFigs. 1 and 2, the carriage 12 is moved from the boat to the land orfrom the land to the boat by means of the cables 15 and 16. The drumsmay be provided with ratchet wheels a, 7) and suitable pawls for holdingthe drums in adjusted position.

As shown in Fig. 3, the carriage co1n prises a link 35 connected tocarriages 36 having pulleys 37 to run upon the cable 5, and suspendedfrom the hooks 33 are suitable grapples 39 for engaging a bale ofcotton, hay or other similar material.

From the foregoing it will be obvious that a loading and unloadingapparatus made in a carrier suspended from said pin, a trolleyaccordance with my invent-1011 can be quickly Wire for said earriege,and means for moving set up and taken down and Wlll operate the letter111 opposite directions.
